My supermarket is connected to all worlds, and I've won so much money handing it over to the st

Before Gu Xixi's social anxiety could even surface, she was infected by the kind, gentle, and encouraging gazes of the merfolk and started dancing randomly along with them.

She imitated all the actions, and her smile was truly radiant; she was so happy, genuinely happy.

After finishing her dance and returning to her seat, Gu Xixi noticed a little mermaid standing next to her, holding a coral bracelet and offering it to her.

"Is this a gift from you?"

The little mermaid nodded and placed the bracelet in Gu Xixi's hand. Her skin was delicate, and it shimmered with the light of fish scales.

As soon as Gu Xixi sat down and put on the bracelet, she heard her ask, "Gu Xixi, our Mermaid King said you are a very, very good human. I also think you are very good. Can you stay in our underwater city and become the Mermaid Queen?"

"We will love you as much as we love His Majesty the Mermaid King."

Gu Xixi gasped in shock. She turned to look at Cang Lin, the Mermaid Emperor. Cang Lin chuckled, his eyes mocking, "I believe my people are right, and I'm willing!"

You're kidding me!

"Don't think I didn't see you smirking," Gu Xixi thought to herself. Turning her head, she saw the little mermaid girl's pleading eyes and shook her head firmly. "No, I still want to go back to my world."

"Why? Our underwater world is wonderful!" the little merman began to tout the advantages of the underwater city. The other mermen nearby chimed in with their own recommendations.

"In our underwater city, every merman has only one partner, forever and ever, and so does His Majesty the Merman King."

"We can live for a very, very long time. If you become a mermaid, you can eat the Beauty Pearl. If you eat it, you can stay young and beautiful forever."

"We still have..."

……

"Because, because I have someone I like, so I can't stay for anyone else. Your Mermaid King is so good, and the underwater city is so good, there will definitely be other better mermaids to come and become the Mermaid Queen."

Gu Xixi politely declined.

The transparent figure that had just appeared beside her vanished in an instant.

"Alright." The little mermaid girl left disappointed, but the Mermaid King laughed heartily. "Please don't mind them. Their feelings for you are just like appreciating a very good thing."

"When they asked you to become a merman, they only thought that I, the merman king, am the most noble thing in the underwater world, and only the best thing and the highest position are worthy of you. They didn't mean anything else."

"Oh, I see," Gu Xixi shook her head. "It's alright, she's very cute too. By the way, I'd like to wander around after the banquet, is that alright?"

"What are you looking for?" The Mermaid King saw through Gu Xixi's purpose at a glance. "I always remember you saying that you were a merchant. This time you came to the underwater city to open a supermarket, which is convenient for my people. I can help you with whatever you want."

“I want methane hydrate, which is…” Gu Xixi described the characteristics of methane hydrate, and then took out her phone to show the Mermaid King related pictures.

The Mermaid King understood, and even felt a bit surprised. "I'm willing to do this business with you. It turns out these things are useful to you. But in our ocean, they are a huge hidden danger."

"Ten kilometers away from our underwater city where we merfolk live, there is a large area of ​​these things on the seabed. They are very dangerous and can explode unexpectedly, causing tsunamis... Our lives are greatly affected every time."

The Mermaid King recounted the story in detail, then took out a map of the underwater city and pointed it out to Gu Xixi.

Gu Xixi immediately gestured to Chu Feng, who then led Old Yang behind Gu Xixi to look at the map together.

"If you can take all the combustible ice from these areas, our merfolk world will be grateful to you for generations to come. As for the harvesting, we have a magical merfolk army that can help. But how to store and transport it is your business."

After the Mermaid King finished speaking, Old Yang also finished calculating on his fingers, "If all the combustible ice in these areas were utilized, it would be a huge energy resource, but there would be dangers in storing it..."

Old Yang was in a dilemma. Modern technology hadn't solved this problem yet... but he had to do it despite the risks, since every energy source carries risks.

Gu Xixi frowned, then relaxed. "After the banquet, you should first investigate the amount of energy. As for storage... we can try using a water storage sphere."

That's futuristic high technology; the material is unknown, but it's estimated to be able to store all the combustible ice, and it's safe.

If that doesn't work, but the resources are plentiful enough to be worth mining, then we should ask about jadeite.

After all, if the future technology is 300 years ahead of the world, and they have already exhausted their own Earth's energy resources, then have they also encountered the problem of combustible ice?

I can ask first thing tomorrow morning, there's still enough time.

"Alright." After the group discussed it, Chu Feng relayed the message, and the banquet continued. Gu Xixi swayed to the music and asked, "Your Majesty, where would you like me to open the supermarket?"

Cang Lin pointed to a square in the middle of the underwater city on the map. "This is where the flow of people is concentrated. For merfolk from all directions, the distance is the same, which is fair. Let's go here."

Gu Xixi nodded, then summoned the system in her mind: [System, System Bro, time to get to work! The Fa Da Cai Supermarket has selected landing coordinates: Central Plaza of the Underwater City in the Mermaid World.]

[Okay, copying the supermarket... The "Get Rich Supermarket" installation is complete. Since this is a reward-based transmigration, this world is a mission-free world. Friendly reminder: the supermarket's operating period remains three months.]

【it is good. 】

"Canglin, the supermarket is already open, right in the center of the square. You can go and take a look after the banquet." Gu Xixi turned to face the Mermaid Emperor. "I'm going home tomorrow morning. The rest of you will stay here to run the supermarket for three months. I'll have to trouble Your Majesty to take care of it."

"I will naturally make them feel at home." The Mermaid King nodded his arrogant chin a few times, agreeing to the promise. This was great, as it would save him from having to go to the Fortune Supermarket every day to haul goods for his subjects.

Even His Majesty, a person of great honor, needs to get his beauty sleep.

These hard times are finally over. The Mermaid King's lips curled up, and he couldn't help but smile. Gu Xixi was puzzled. What was this arrogant guy secretly gloating about?

Meanwhile, at a well-known university on modern Earth.

Professor Wang teaches one class per week, and it's his last year teaching, so the opportunity is extremely rare. As a result, the classroom is always packed with students.

Holding their books, their puzzled gazes kept gathering at the classroom door.

Professor Wang, who always arrives early, is still nowhere to be seen. The bell will ring in just one minute, and this is unprecedented.
